Winner-take-all system


A winner-take-all or system is a type of voting system where representation in a governing body or electoral district is only awarded to the candidate or party that receives the most votes. Although such systems are sometimes called "majoritarian representation" or "majorizing" systems, winners do not always have the support of an absolute majority, as it is possible for a plurality to select winners. Winner-take-all systems are contrasted with proportional representation systems, wherein control of the body or district is divided proportionally to the number of votes.
Winner-take-all systems are criticized by economists, political scientists, and citizen activist groups for allowing potentially disproportionate and undemocratic results, as small pluralities can obtain complete power over a governing body, leaving the majority of voters unrepresented. Furthermore, political scientist Maurice Duverger argued that winner-take-all systems lead to two-party systems, a theory termed Duverger's Law.

Definition and types

A voting system is winner-take-all if representation is only awarded to the candidate with the largest vote share. Since single-winner voting systems can only select one winner to represent all voters in a given body or district, all such systems are by definition winner-take-all. This includes both first-past-the-post and single-winner ranked voting methods.
A multi-winner voting system can still be winner-take-all if a plurality of voters can coordinate to only elect representation for themselves. This includes plurality block voting, where voters can select as many candidates as there are open positions, and can win all seats by simply selecting all the candidates of their preferred party. In addition, although single non-transferable voting systems can produce results where a plurality elects every seat, this requires poor coordination of minority factions, so it is not strictly winner-take-all.
If the members of a body of representatives are each elected from a winner-take-all electoral district, the system as a whole may not reflect the winner-take-all principle wherein the party with the most votes, whether plurality or majority, receives all or even most of the seats. If a sufficient number of votes from the plurality or majority are wasted in each district a minority of voters can win a majority of seats in the governing body.
The principle of majoritarian democracy does not necessarily imply that a winner-take-all electoral system needs to be used, in fact, using proportional systems to elect legislature usually better serve this principle as such aims to ensures that the legislature accurately reflects the whole population, not just the winners of the election and the majority rule is then used within the legislature. The most widely accepted modern views of representative democracy no longer consider winner-take-all representation to be democratic. For this reason, nowadays winner-take-all representation is most often used in single-winner districts, which allows nationwide minorities to gain representation if they make up a plurality or majority in at least one district, but some also consider this anti-democratic because of the possibility of an electoral inversion.
Winner-take-all and proportional systems are the most commonly used voting system worldwide, followed by mixed electoral systems, which usually combine winner-take-all and proportional representation, although there are mixed system that combine two winner-take-all systems as well. Winner-take-all representation is also contrasted with proportional representation, which provides for representation of political minorities according to their share of the popular vote and semi-proportional representation, which inherently provides for some representation of minorities. Within mixed systems, mixed-member majoritarian representation provides semi-proportional representation, as opposed to mixed-member proportional systems.

At-large winner-take-all representation

Historically the first multi-winner electoral systems were winner-take-all elections held at-large, or more generally the multiple non-transferable vote.

Decline

Until the first half of the 19th century, the classic winner-take-all system of block voting began to be more and more criticized. This introduced in two senses:
  • a first possibility was to reduce the size of the constituencies, so to divide the election in many local contests, and consequently increase the possibility for the minority to win in some areas. At-large elections were substituted by many multi-member constituencies and, finally, by single-winner electoral districts.
  • Cumulative voting and the single non-transferable vote were introduced to allow minorities to have some representation, creating the first semiproportional systems. By allowing minority groups to concentrate their votes on a few candidates, such systems ended the winner-take-all nature of the
  • Eventually, proportional representation methods were developed in both Europe and separately in the United States
The version of block voting using electoral lists instead of individual candidates was almost completely replaced by party-list proportional voting systems, which fully abandon the winner-take-all ideal in favor of equal representation. However, with the majority bonus or majority jackpot types of mixed system, this type of winner-take-most system has partially reappeared in certain electoral systems.

Winner-take-all districts

Winner-take-all representation using single-winner districts is the most common form of pure winner-take-all systems today, with the most common being single-member plurality.
However, due to high disproportionalities, it is also considered undemocratic by many. In Europe only Belarus and the United Kingdom use FPTP/SMP to elect the primary chamber of their legislature and France uses a two-round system. All other European countries either use proportional representation or use winner-take-all representation as part of a mixed-member winner-take-all system or a mixed-member proportional system. However, other European countries also occasionally use winner-take-all systems for elections to the secondary chamber of their legislature and sub-national elections.
Winner-take-all system are much more common outside Europe, particularly in the countries of the former British Empire, like Australia, Bangladesh, Canada, Egypt, India, Pakistan and the United States.
Nowadays, at-large winner-take-all representation is used for national elections only in the Senate of the Philippines, while it is sometimes still used for local elections organised on non-partisan bases. Residual usage in several multi-member constituencies is reduced to the election of the Electoral college of the President of the United States. Block voting is also used to elect a part of the assemblies in the regional elections in Italy and France.
